ART. 1

A substitute who desires to enter shall report to the scorer, giving his/her number.

a. Between quarters, at halftime and during a time-out, the substitute must report or be in position to report to the scorer, prior to the warning signal which is sounded 15 seconds before the end of the intermission or the time-out.

NOTE: When the substitute(s) is not properly reported, the player(s) in the game at the conclusion of the quarter when the time-out was granted shall begin play for the new quarter after the time-out.

b. Substitutions between halves may be made by the substitute or a team *representative.

c. During multiple free throws resulting from personal fouls, substitutions may be made only before the final attempt in the sequence and after the final attempt has been scored.

EXCEPTION: When a player is required by rule to be replaced prior to administering the free throw(s), then all other substitutes who have legally reported may also enter the game.

d. If entry is at any time other than between quarters, and a substitute who is entitled and ready to enter reports to the scorer, the scorer shall use a sounding device or game horn, if, or as soon as, the ball is dead and the clock is stopped.

e. A captain may request a defensive match-up if three or more substitutes from the same team enter during an opportunity to substitute.
